Geek that's excellent news re the ovary playing ball! 
Thanks Geek, Maybe and Cups for the OPK information. So I either missed the surge... or there's not been one yet and the levels have just gone up and down a bit. Hmm!
I have a big bag of cheapies (the ones you recommended!), and may well try testing twice a day next cycle. Or if the LH appears to start rising again!
Loopy, I suspect my cycles could easily be out of whack (although they got back to normal quite quickly last time I came off of the pill, but I didn't have a DD and hadn't been BFing then!). I was using the OPKs to try and see if something was happening. Something has happened, but I don't know if it's a surge (with no strong positive bit!) that I've partly missed, or just a small wave
. Either way, something's happening, which is good at least!
Maybe, I temped when TTC DD, but always did it first thing in the morning, and was aware it may not be too accurate if DD woke me up at silly o clocks. However, Geek (I think?) has since mentioned that you can do it during waking hours.. and I forgot last cycle, and haven't been able to find my thermometer.. until this afternoon! I suppose doing them this cycle isn't particularly useful now.. so maybe for the next one!
